IVIODEOF SECURING SHEET-METAL COVERINGS FOR ROOFS.

Specification lof Letters Patent No. 15,988, dated October 28, 1856.

To all whom t may concern.' i i i Be it known that we, WILLIAM H. Thiss- LER and JOHNSTEWART, of Fairview, in the county of Erie and State of Pennsylvania, have invented anew and Improved Method of Securing Sheet-.Metal Coverings to Roofs; and we do hereby declarethat the following is a full and exactdescription thereof, reference being had to the accompanying drawings, making part of this specification, Figure l being aiplan, loo-king across the slope of the roof, of a portion of sheet-metal covering secured to the roof in our improved manner; Fig. 2, a similar lan, looking up the roof; Fig. 3, a section 1n the linea, w of Fig. l; Fig. 4, a section..

in the line y, 'y of Fig. 2. j

Like letters designate corresponding parts in all`the figures.

Our improvement relates, first, to a ready mode of uniting the separatesheets, so as to form tight horizontal joints upon'a roof,

which` will offer no obstruction to the de scent of the water, nor to the formation `of use of solder, and` consequently of cheaper` and more rapid construction than ordinary.

The second feature of our invention consists in the improved mode of forming the lock joints running up and down the roof. Vhen strips of united sheets A, A, have been formed of sufficient length to reach from the ridge to the eaves, one edge of each is rolled into a nearly cylindrical shape a.,

j While the other edge Z9, is turned up nearly at right angles as4 shown in Fig. 3. After one strip is applied to the roof, the edge b, of the next strip is then inserted beneath the:

i scroll edge a, of the fastened,` strip, from one metal having one end turned upinto a i scroll-like form to fit the scroll a, of the covering. A sufficient number of these clips is inserted in the scroll a, and then fastened to the roof by nails cZ. The next strip of covering laid down covers these clips, and another set thereof, in turn, secures this last strip to the roof. In this manner the covering is securely fastened to the roof without `exposing a nail, around which to allow the water to penetrate through the covering.

Vhat we claim as our invention, and desire to secure by Letters Patent, is*

l. The double lapping joint o, for uniting the sheets of metal without solder, substantially as herein described.

2. IVe also claim the combination of the scroll and wing edges a, for uniting the strips of covering, substantially as specified. The above specification of our improved mode of securing sheet-metal coverings to roofs, signed and witnessed this 18th day of August 1856. y
